the trunk to keep diffs small.

Move ex_data.c entry from "NEEDS PATCH" to "OPEN ISSUES".

- 0.9.6a is under development
- a couple of illegal includes of <openssl/e_os.h> should be purged
- ex_data sucks

entries are still current or what they are about:

    o  non-blocking socket on AIX
    o  $(PERL) in */Makefile.ssl

So I'll remove them for now.

At the same time, add VMS support for Rijndael.

Whether Steve is still working on 'proper' verification is up to
him to decide ...
